Disclosed herein is a capacitor mounting type inverter unit having a cooling block, an inverter including a plurality of phases of switching circuits provided on the cooling block, and a smoothing capacitor. The inverter unit includes a cover having a first recess for accommodating the inverter and a second recess for accommodating the smoothing capacitor. The second recess has a depth larger than that of the first recess. The second recess is filled with resin in the condition where the smoothing capacitor is accommodated in the second recess.

Capacitor mounting type inverter unit having a recessed cover

In an inverter apparatus in which a three-phase inverter main circuit having a plurality of arms comprises a plurality of semiconductor chips for electric power, one arm of the three-phase inverter main circuit includes IGBTs and diodes of semiconductor chips having a size of 10 mm by 10 mm or less with the semiconductor chips connected in parallel, while the IGBTs and the diodes are bonded to a conductor having a thickness of 1.5 mm or more and 5 mm or less, and the conductor is glued to a cooler through an insulating resin sheet containing ceramics.
